Courtesy lights have a 3 position switch 1 is for doors open --on /off 2 is for light off permanent and 3 is for light on in car permanent for reading etc. Other than that check the door switches for a permanent earth fault.

Where is the bcm located on a 95 buick roadmaster? My interior lights stay on and I want to troubleshoot by disconnecting the bcm.


Your vehicle has no BCM ! Which interior lights ? dome , courtesy , insturment panel ? Dimable light's ? Stuck door switch ! Find a wiring diagram at http://bbbind.com/free_tsb.html ! Do you know how to do basic automotive electrical testing ? Videos on youtube . The wiring diagram is showing a dome courtesy lamp relay , if the contact's were stuck closed the light's would stay on . But there is no BCM .

2001 gmc jimmy clock stays on after door is opened and dies out battery, what could be wrong?


No other lights on ,dome, courtesy etc...
Battery Rundown Protection/Inadvertent Power
In the event that any of the interior lamps supplied voltage by the inadvertent power relay and ground from the courtesy lamp relay were to remain on when the ignition is OFF after a period of 20 minutes, the BCM will deactivate the inadvertent power relay turning OFF all of the lamps on that circuit to prevent total battery discharge. Only when the ignition switch is cycled back to the RUN position will the BCM reset the internal timer and reactivate the inadvertent power relay. When the inadvertent power relay is not energized, the BCM utilizes the inadvertent power courtesy lamp supply voltage circuit to monitor for a courtesy lamp switch request signal. If a courtesy lamp switch is activated, the BCM will receive the signal to energize the inadvertent power relay by grounding the control circuit.

Can't get dome lights on when door is opener even with override switch off?


The following lamps may be manually turned ON by placing the interior lamp switch in the ON position, or by opening a door while the switch is in the AUTO position.
?€¢
The dome lamp


?€¢
The liftgate lamps


?€¢
Courtesy/map lights

The courtesy lamp supply voltage circuit of the body control module (BCM) supplies battery positive voltage to the dome lamp, the liftgate lamps, and the map lamps. When any door is opened, the door jamb switch contacts close providing a door open input to the BCM. The BCM then provides a ground to the interior lamps with the switch in the AUTO position. The interior lamps receive a ground at G401 with the switch in the ON position.
Important: If the liftgate is opened after all the modules go to sleep, the dome light will not come on. The liftgate ajar switch input to the BCM will not wake up the BCM once it has gone to sleep, so the dome light will not come on. Once the BCM gets an input to wake it up, from remote keyless entry (RKE) or a door handle, the dome light will turn on when the liftgate is opened.
If the driver inadvertently leaves any interior lamp ON, the BCM will turn it OFF after a 20 minute time-out.
The courtesy lamps will turn OFF immediately if the ignition switch is turned to the ON position or approximately 20 seconds after all doors are closed.
The courtesy lamps are controlled by the body control module (BCM). Inputs from the dome lamp switch and the door ajar switches are monitored by the BCM. When a door ajar switch is closed, or the dome lamp switch is turned to the ON position, the BCM supplies the B+ for the courtesy lamps.
With out a factory Tech2 scan tool or equivalent an knowing how these systems work ,you best bet is to take your vehicle to the dealer or some other ASE certified repair shop !

In my GmC S-15 Jimmy the dome light and courtesy lights stay on when car is off and doors are shut help me fix this


Your door switch is made into the door latch, you might try spraying WD-40 into the drivers door latch and work the latch open and closed. You will probably end up having a new latch installed though.

Dome light and key in ignition tone won't quit.


Yes, I would lean toward a stuck drivers door latch. Your door open switch is located in the latch itself and the ding is a reminder your key is in the ignition so you don't lock them in the vehicle when you lock the door. even though your door is shut, the truck still thinks it is open. sometimes spraying the latch with some WD-40 will get it freed up and working again, but a new latch might be in your future.

Plugged in lights on ,,out lights off. Then have the unit tested. or replace. If there was ever a power surge the caps could have blown.

2001 Sequoia, door ajar light goes off, but dome light stays on. Door ajar light comes on with slight pressure against closed door. Can replacing the door jam switch solve this problem? Why would the door...


To temporarily solve the light problem, I taped a washer to the inside of the door where the door hits the plunger on the light switch. A permanent solution would be to drill a hole in the door at this spot and put a self taping screw in that will trigger the switch sooner. I figured out the reason the dome light stayed on is due to the courtesy light timer and the lights would have eventually gone off.

2004 crown vic interior lights stay on


Don't think you have a door ajar switch problem , more then like the lighting control module is the culprit . Does the door ajar light on the instrument cluster stay lit ?
The interior lighting can be separated into two distinct modes of operation: the courtesy lighting and the demand lighting. The lighting control module (LCM) controls all of the interior lighting in the vehicle, as described in the following text.
The front dome lamps, rear reading lamps, and instrument panel courtesy lamps, can be illuminated either by opening any of the vehicle doors (courtesy lamp function) or by depressing the headlamp switch (demand lamp function).
When any door is open, the door ajar switch grounds an input to the LCM which then sends power to the courtesy lamps. The voltage sent to the courtesy lamps gradually increases from 0 volts to 12 volts within 500 ms (± 50 ms), to achieve the theater lighting effect. When the door(s) are closed the door ajar switch(es) break(s) the ground to the LCM input which then gradually reduces the power from 12 volts to 0 volts within 5 seconds. (± .5 second).
When the headlamp switch is depressed it grounds an input to the LCM which in turn sends 12 volts to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps. When the headlamp switch is depressed a second time, it breaks the ground to the LCM input which then ceases to send power to the front dome lamps, rear reading lamps, and instrument panel courtesy lamps.

The battery saver will disrupt power to the courtesy lamps after 10 minutes, the demand lamps after 30 minutes, and the headlamps after 10 minutes. Turning the ignition switch to the RUN or ACC position will terminate the battery saver feature by disabling the interrupt timers and reinstate power to the lamps.

No The system is operating correctly. C2 TEST DOME LAMP SWITCH Depress the dome lamp switch.
